The objective of the paper is to apply the statistical procedure of ridge regression to a multivariate model of criminal activity. The explanatory variables are of an economic, apprehension, and seasonal nature. The Time Shared Reactive On Line Laboratory (TROLL) computer package was used in ...
On multivariate ridge regression 来自 掌桥科研 喜欢 0 阅读量: 52 作者: Y Haitovsky 摘要: A multivariate linear regression model with q responses as a linear function of p independent variables is considered with a p × q parameter matrix B. The least-squares or normal-theory maximum ...
Often a set of features (multiple regressions) or polynomial regression (applying a various set of powers in the features) is used for making better model fit. For these models are expected to be susceptible towards over fitting ridge regression is used to reduce it. This paper thus directs ...
It is numerically shown that these modified procedures perform very well in the sense of selecting the true model in large dimensional cases. 展开 关键词: Akaike information criterion Large dimension Mallows' C-p Multivariate linear regression model Selection of variables DOI: 10.1080/03610926.2011....
Generalized ridge (GR) regression for an univariate linear model was proposed simultaneously with ridge regression by Hoerl and Kennard (1970). In this paper, we deal with a GR regression for a multivariate linear model, referred to as a multivariate GR (MGR) regression. From the viewpoint of...
(n = 75–500); this suggestion is made on the basis of analyses of a selected subset of multivariate cognition/RSFC associations with larger effect sizes, using their preferred method (ridge regression with partial correlations) in a demographically more homogeneous, single-site/scanner sample...
A new multivariate regression model, named Error Covariance Penalized Regression (ECPR) is presented. Following a penalized regression strategy, the proposed model incorporates information about the measurement error structure of the system, using the error covariance matrix (ECM) as a penalization term....
Purpose The aim of this study was to develop a multivariate logistic regression model with least absolute shrinkage and selection operator (LASSO) to make valid predictions about the incidence of moderate-to-severe patient-rated xerostomia among head and neck cancer (HNC) patients treated with IMRT...
Consistency of M-Estimates in General Regression Models This paper extends the results of Chen and Wu [1] concerning consistency of M-estimators in the linear regression model. We consider M-estimators defined b... F Liese,I Vajda - 《Journal of Multivariate Analysis》 被引量: 54发表: 1994...
Model selection in kernel ridge regression 2013, Computational Statistics and Data Analysis Citation Excerpt : Hundreds of predictors are often available, and economic theory does not usually provide guidelines concerning which variables should or should not be included in a model.
